To oli w71 om it m (17,/ fonce/rn.'

le it known that I. DAVID SCi-murali, a subject ol the lzar ot' Russia,residing in the borough ot Bronx, in the city ot' New York, titan ofNon' York. hare made certain new and ust'fl'ul Improvements in Sacity-Razors. ol' which the Yl,`f. l..lo\\ing description aspecilieation. reference. being had to the aoeorumuying drawings. 1

'llu invention relates to that class of lvl/:o s in wh' Vli the cuttingblade is a separate part and is held or clamped in position by a ,handlewhich presses two plates together on the blade.

The ohjert of the invention is to avoid the bonding of the blade and atthe same time steady the ri'itting blade in its position in the holder`p My iinlum'enients also reduce the number nl parts required to hold therazor blade in piave The improvements are also designed to ru'otect theuserfrom cutting with the corners of the blade by extending the guardplate past the ends of the blade.

la the drawings Figure l. is a front elevation oi" my derive; Fig, is anend eleva tiouf li'ig. is a central cross-lsection of Fig. l. Fig. fl across section through Fig. il :in the line .r Y fr and Fig. 5. is adetached View ol they damping plate.

The lullder of the cutting blade made in two parts. (lne ot whicheomprises the handle A integral with a guard plate B.

' Along nach side of the guard plate B are lingers u, o set at an angleas shown 1n Fig. 2.

C the flaulping plate having a central pin i whieh is threaded at itsfree end. The plate (l a nd pin .71 are integral and form one piece ofthe apparatus. Between the two plates ll and is clamped the cuttingblade l). `which proiects over the lingers a. The handle A `nollow andreeeives a tube E introdueell' from the outer end. The tube E terminatesin a threaded end adapted to serew into the end ot" the handle A andprovided with a roughened nut r?. The blade D is pierced at its centerwith a hole through which the pin l) passes. About midway in the lengthof the handle A is located a screw Patented Dec. 1, 1914.

as shown at h. The pin t of the clamping plate (his made integral withit or rigidly secured to it.

The guard plate B is of the proper length to lie within the lips orconfining rims l1., h, at the ends of the clamping plate C, and theguard plate B, has its ends shaped to fit ex! actly within the spaceinclose'd by the rims. The razor blade should be of the exact length ot'the guard plate and shaped at both ends lo Ht snugly Within the rimsl1., The holding device it will be seen thus consists of two parts onlyg or at least only two parts which are separated when in changing therazor blade, The. razor blade forming a removable part held between thetwo plates of the holder. The handle and the guard plate do not varytheir position as regards eael` other, but the clamping plate C isadjusted ond l' rom the guard plate by inea ns of its central stem b,which passes through the hole in the blade.. The ends of the cuttingblade are shaped to fit snugly within' the inolosing rims h, il.. of theclamping plate C so that it will not have any lateral or circular movement when the clamping platos are pressed upon it.

The end ngers of the guard plate B are notched and'extended pas! theends ot the raised rims l, k. of the clamping plate C, at the points z'.7', Fig. l. so that a portion of the guard plate lies between the o-geeshaped raised rims and a portion across the end* thereof. This causesthe two plates to snugly when -superixnposed and projects the fingerspast the ends of an intervening cuttingr blade.

Hai ing desuribed my improvements what I elaini as mv invention anddesire to secure by Letters Patent is:

In a safety razor blade holder, an usr clamping plate having raisedinclosing end and held in the handle h3' n. mbe E and screw lips and :icentral stem rigidly attached cap f5', substantially ihereto said stemterminating in a threaded end, in combination with a handle and guard 5plate rigidly attached to the handle, a screw nut G, having u circulargroove g positioned down and deacrifed.
